Go to: Tennessee Passes ‘Monkey Bill’ To Teach The ‘Controversy’ On Evolution And Climate Science

Comment 58 by Tryphon Tournesol :

Through what arguments are those controversies established?

I would imagine by personal opinion and general disregard of evidence, any evidence working against them being treated as not existing and therefore there is "no evidence" for climate change and evolution.

Hm, one should demand to teach controversies in every subject, and then teach about the "controversy" that Mary mother of Jesus was a virgin and every such little bitt. Shine some light on every single religious controversy in religion class and keep it that way until they agree not to teach "controversies" in a subject based only on the fact that some might disagree and calls it a controversy..

I believe you, no worries. I was just making a point in peoples understanding of statistics, not actually testing you:)

Comment 80 by mmurray :

N patients With disease P(D) N
Without disease P(nD) N
With disease and test positive P(T+|D) P(D) N
Without disease and test positive P(T+|nD) P(nD) N So

P(D|T+) = P(T+|D) P(D) / ( P(T+|D) P(D) + P(T+|nD) P(nD) )

Substitute in numbers:

.9 x .008 / ( .9 x .008 + .07 x .992 ) = .094 (approx) or 9.4 %

Or with numbers 1000 patients With disease 8
Without disease 992
With disease and test positive 7.2
Without disease and test positive 69.4 So you want 7.2 / 7.2 + 6.94 = .094 or 9.4 %

EDIT: I did it before I read the answer. Honest.

I think we agree then.

It is a bit to easy to attack anyone that questions medical procedures that on the face of it seems very unproblematic.

It is very important that everybody who is screened in such a program knows the actual benefit of it, and also the costs. This goes for cost to society as well, one might be able to use the funds taken up by screening to save more lives in another more efficient way.

@ hungarianelephant,

Sorry, you did get the correct probability to get cancer but you mistyped it, it is not 94% chance of having cancer given a positive test but more like 9.4%.

Sorry for not checking better before responding.
